Theory of Machine The displacement of the reciprocating roller follower, when it has contact with the straight flanks of the tangent cam, is given by (where r₁ = Minimum radius of the cam, r₂ = Radius of the roller follower, and θ = Angle turned by the cam from the beginning of the follower displacement) (r₁ + r₂) (1 + cosθ) (r₁ - r₂) (1 - cosθ) (r₁ - r₂) [(1 - cosθ)/cosθ] (r₁ + r₂) [(1 - cosθ)/cosθ] (r₁ + r₂) (1 + cosθ) (r₁ - r₂) (1 - cosθ) (r₁ - r₂) [(1 - cosθ)/cosθ] (r₁ + r₂) [(1 - cosθ)/cosθ] ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A torsional system with discs of moment of inertia I₁ and I₂ as shown in the below figure, is gear driven such that the ratio of speed of shaft B to shaft A is 'G'. Neglecting the inertia of gears, the equivalent inertia of disc on shaft B at the speed of shaft A is equal to I₂/G G.I₂ G².I₂ I₂/G² I₂/G G.I₂ G².I₂ I₂/G² ANSWER DOWNLOAD EXAMIANS APP
